[MC Java 1.12+] Two Mushroom Islands Close to Spawn

Seed "2325" starts you on a tiny, barren island in the middle of an ocean. To even get a tree, you need to swim a ways. I only found one tree on the next island I went to, and only got one sapling, so be prepared for some very frugal tool use at the beginning. There are two nearby ocean monuments, one near the spawn island, one due east of spawn, so swim carefully!

If you swim either east or west, you can find mushroom island biomes, which will at least keep you safe and well-fed while you wait for your one sapling to grow and farm enough wood to be able to keep making tools. The western one (the one I didn't pick, naturally...) has several mineshafts off the coast.

One of the strongholds (2192, -896) is 34 blocks away from an ocean monument (2216, -872), which may be helpful for people attempting the How Did We Get Here? challenge. There's only one eye in the portal, though.
